In our system, we use linux quota to limit users file usage. However, quota database has inconsistencies with file usage of users. Sometimes user has no data, however quota database shows 4KB of usage.

On this problem, quotacheck is recommended. However, quotacheck fully checks the disk. If there are too many files and users, also user files frequently changing; online mode of quotacheck can’t fix inconsistencies.

In Computer Communications course, we have been wanted to present a SIGCOMM paper and write a report about it. We choose this paper, Named Data Networking. The paper was a summary of all works done related to Named Data Networking.

This is our report. We had limited time to write this paper, I can consider it incomplete. It may have better. It can give more information and give sophisticated point of views about NDN. Regardless, it was a good work about NDN.
